Description

Technical Field

[0001] This invention relates to the field of deep-sea aquaculture technology, specifically to a ribbonfish breeding system based on a marine ranching platform. Background Technology

[0002] Hairtail is a migratory fish that typically inhabits relatively deep waters. This lifestyle and the deep-sea environment it inhabits present numerous challenges for artificial breeding. Furthermore, with the increasing depletion of global fishery resources, traditional near-shore fisheries are struggling to meet market demand. Deep-sea aquaculture platforms, as an emerging fishing method, can reduce the overexploitation of near-shore fishery resources and contribute to the protection of the marine ecosystem. Breeding hairtail using deep-sea aquaculture platforms can alleviate pressure on near-shore aquaculture and reduce conflicts with other marine economic activities. Therefore, existing technologies provide numerous deep-sea aquaculture devices to address the problem of excessive pressure on near-shore aquaculture. For example, existing technology US20240359779A1 provides a cage aquaculture platform that comprehensively utilizes marine new energy sources, including a wave power generation device, a platform body, a solar power generation device, a wind power generation device, aquaculture cages, and a mooring system. Wave power generation devices are installed around the main body of the platform, solar power generation devices and wind power generation devices are installed on the upper part of the main body of the platform, and aquaculture cages are installed underwater below the main body of the platform. The technology provided by this patent enables the aquaculture equipment to be used continuously in the deep sea for a long time, but there is still room for improvement in the stability of the aquaculture equipment in the deep sea environment. Summary of the Invention

[0003] The purpose of this invention is to provide a ribbonfish breeding system based on a marine ranching platform, which has a high degree of ecological behavior simulation and is resistant to typhoons and ocean currents, and can be used continuously in deep-sea environments.

[0004] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: a ribbonfish breeding system based on a marine ranching platform, comprising a second base frame, a buoyancy component below the second base frame, and a culture cage connected below the buoyancy component. The buoyancy component includes a first mesh plate with mesh openings, and the first mesh plate is covered with a hollow floating frame. The second base frame of the present invention has buoyancy, enabling it to carry the buoyancy component and the culture cage to the target sea area for ribbonfish culture. The second base frame floats on the sea surface, and the buoyancy component adjusts the culture water level according to the habits of the ribbonfish by controlling its buoyancy. This allows for finding more suitable natural conditions for the ribbonfish's growth in the deep-sea culture environment, thus promoting its growth, development, and reproduction. The ecological behavior simulation is highly accurate, and the culture cage can rise and fall in the water, exhibiting strong resistance to the harsh deep-sea environment and enabling continuous use in the deep sea. The buoyancy component above the culture cage in this invention... While providing buoyancy adjustment, the first mesh plate is installed to enhance the structural strength of the aquaculture cages and prevent the cages from rubbing against the second frame on the water surface and damaging the netting after they float up. The first mesh plate has openings with an opening rate of 60%-90%, which can balance the light and water exchange at the top of the aquaculture cages. More importantly, the first mesh plate can guide the feed. After the feed is put down, it is guided through the openings of the first mesh plate into the aquaculture cages below, thus guiding the feed to sink and preventing it from scattering quickly.

[0005] According to one embodiment of the present invention, a connecting pipe is provided on the float frame, the connecting pipe communicating with the hollow part of the float frame and being connected to a control component through a first pipe body. The control component has a pump body. A first connecting block is provided on the float frame, the first connecting block having a groove-shaped mounting hole for connecting to the bottom of a first base frame or a second base frame. The pump body is a water pump, and the water volume inside the float frame is controlled by controlling the water pump, thereby controlling the buoyancy of the float frame to control the height of the aquaculture net cage at the bottom of the buoyancy component in the water.

[0006] According to one embodiment of the present invention, the second base frame has buoyancy and is equipped with a control component. The control component houses sensors such as a water pump, a positioner, a signal transceiver, a control unit, a water quality sensor, and a temperature sensor. The water quality sensor is connected to the water pump to detect the amount of water pumped. The control component has a housing, on which a photovoltaic panel is mounted. A battery is located inside the housing and can be connected to a power generation component on the second base frame. The energy generated by the photovoltaic panel and the power generation component is stored in the battery to power various electrical devices. The power generation component on the second base frame is a wind power generation device. A feeding device is also provided on the second base frame, containing a certain amount of feed. The control unit within the control component controls the feeding device to feed the feed at fixed times and locations. Farmers need to replenish the feed regularly. A sensor can be installed within the feeding component to detect the remaining amount of feed.

[0007] According to one embodiment of the present invention, the first base frame is arranged in a surrounding manner around the outer side of the second base frame. This can distribute the load between the second base frame and the first base frame. By increasing the overall buoyancy, the first base frame reduces the load-bearing pressure on the second base frame, preventing the second base frame from overturning or sinking due to the weight of the aquaculture cage or the impact of wind and waves. The bottom of the first base frame is connected to the buoyancy component via a first rope, and the buoyancy component can also be connected to the second base frame via the first rope.

[0008] The first base frame has elongated, strip-shaped floats arranged around it. Adjacent elongated floats are connected end-to-end to form a layout that surrounds the second base frame. Vertical railings are arranged around the surface of the elongated floats, and buoys are located below the elongated floats. The elongated floats can connect to a first connecting rod or to a first connecting plate extending from the second base frame, thus connecting the first and second base frames. The first base frame is arranged around the outer side of the second base frame, upgrading from a "single buoy" to a "composite buoyancy system." The arrangement of the elongated floats around the second base frame also creates a space between the first and second base frames. This results in lower water surface fluctuations within this space, reducing the drift range of bait when it is deployed in this area and decreasing the probability of bait waste.

[0009] According to one embodiment of the present invention, the aquaculture cage has at least two cage rings with a spaced-apart circular structure. Adjacent cage rings are connected by a main cage rod. The cage rings and the main cage rod form a cylindrical structure and are covered with a net. The cylindrical cage with no sharp edges, formed by the cage rod and the cage rings, can evenly disperse the impact force of the water flow, reduce the generation of eddies, and reduce the risk of cage deformation. The cylindrical structure helps to form a spiral water flow during water exchange, accelerating the exchange of water inside and outside the cage, increasing dissolved oxygen by 15%-20%, and improving the efficiency of metabolic waste discharge. The number of cage rings can be selected according to the actual cage size to ensure the structural strength of the cage.

[0010] According to one embodiment of the present invention, a first float is provided in the middle of the net cage ring, and a rotatable support rod is provided between the first float and the net cage ring. An extension plate is provided on the outside of the support rod. The support rod can strengthen the structure of the net cage ring, reduce the probability of deformation of the net cage ring, and at the same time, the support rod is linked with the water flow or wind. The swinging may promote the water exchange around the net cage, increase the dissolved oxygen, prevent local water quality deterioration, and be conducive to the healthy growth of fish. During the swinging process of the support rod, the extension plate on its side swings, which can effectively drive away fish-eating birds such as seagulls and cormorants through dynamic visual interference or accompanied by sound, reduce their predation on farmed fish, and reduce economic losses. More importantly, after the feed is put downward, it is guided into the aquaculture net cage below by the support rod and the extension plate, thus realizing the guiding path of the feed sinking and avoiding the feed from scattering quickly.

[0011] According to one embodiment of the present invention, the interior of the aquaculture cage is divided by a partition component. The partition component includes a second float, a second partition mesh plate surrounding the outer side of the second float, and a first partition mesh plate surrounding the outer side of the second partition mesh plate. The first partition mesh plate is placed inside the aquaculture cage and connected to it. By setting a partition component inside the aquaculture cage, different individuals of ribbonfish within the cage can be separated, solving the problem that ribbonfish are ferocious carnivorous fish, and that differences in size can easily lead to fighting when aquaculture is carried out at high density. The second float ensures that the partition component maintains its posture in the water, reducing downward displacement and deformation of the surrounding second and first partition mesh plates under load.

[0012] According to one embodiment of the present invention, both the first and second separating mesh plates have mesh openings, and the mesh opening diameters of the first and second separating mesh plates are different. Proportional setting of the mesh openings of the first and second separating mesh plates can guide the distribution of water flow during water exchange. For example, when the mesh opening of the first separating mesh plate is larger than that of the second separating mesh plate, the flow rate through the first separating mesh plate is larger. This creates a difference in fluid velocity around the first and second separating mesh plates, promoting the movement of excreted waste and other debris above the separating components. This solves the problems of metabolic waste accumulation and overall dissolved oxygen uniformity on the separating components. Furthermore, the resulting difference in flow velocity helps promote fish movement, addressing the issue of reduced density per unit space after stratification and avoiding localized oxygen deficiency, especially when fish congregate at night.

[0013] According to one embodiment of the present invention, a buoyancy support member is provided below the first partition mesh plate. The buoyancy support member has a hollow interior with a float, and its upper end is connected to the first partition mesh plate via a buoyancy connecting rod. The buoyancy support rod can provide buoyancy support for the first partition mesh plate, preventing excessive downward deformation of the edges of the first partition mesh plate and ensuring that the relative horizontal height of each first partition mesh plate is consistent to guarantee effective internal space separation.

[0014] According to one embodiment of the present invention, a first connecting rod or a first connecting plate is arranged around the outer side of the second base frame to achieve connection with the first base frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The second base frame of the present invention has buoyancy, which can carry the buoyancy component and the aquaculture cage to carry out ribbonfish farming in the target sea area. The second base frame floats on the sea surface, and the buoyancy component adjusts the height of the aquaculture water layer according to the habits of ribbonfish by controlling its buoyancy. In this way, more suitable natural conditions for its growth can be found in the deep sea aquaculture environment, which is conducive to its growth, development and reproduction. The ecological habits are simulated with high degree of fidelity, and the aquaculture cage can rise and fall in the water, which has strong resistance to the harsh environment of the deep sea and can be used continuously in the deep sea.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Example 1:

[0029] like Figure 1-7 As shown, a ribbonfish breeding system based on a marine ranching platform includes a second base frame 20, a buoyancy component 40 below the second base frame 20, and a culture cage 30 connected below the buoyancy component 40. The buoyancy component 40 includes a first mesh plate 43 with mesh openings, and the first mesh plate 43 is covered with a hollow floating frame 41. The second base frame 20 of this invention has buoyancy, which allows it to carry the buoyancy component 40 and the culture cage 30 to the target sea area for ribbonfish farming. The second base frame 20 floats on the sea surface, and the buoyancy component 40 adjusts the culture water level according to the habits of the ribbonfish by controlling its buoyancy. In this way, more suitable natural conditions for the growth of ribbonfish can be found in the deep-sea culture environment, which is conducive to their growth, development and reproduction. The ecological habits are simulated with high fidelity, and the culture cage 30 can rise and fall in the water, has strong resistance to the harsh environment of the deep sea, and can be used continuously in the deep sea. The buoyancy component 40 set above the culture cage 30 of this invention... While providing buoyancy adjustment, the first mesh plate 43 is set to enhance the structural strength of the aquaculture cage 30 and prevent the aquaculture cage 30 from scratching and damaging the netting when it floats to the surface with the second base frame 20. The first mesh plate 43 has openings with an opening rate of 60%-90%, which can take into account both the light and water exchange at the top of the aquaculture cage 30. More importantly, the first mesh plate 43 can guide the feed. After the feed is put down, it is guided into the aquaculture cage 30 below through the openings of the first mesh plate 43, thus guiding the sinking path of the feed and preventing the feed from scattering quickly.

[0030] The buoyancy component 40's adjustment scheme for the aquaculture cage 30 in water is shown in Table 1 below. The depth of the aquaculture cage is adjusted according to different scenarios. The summer midday adjustment scheme is used to lower the ambient temperature of the ribbonfish and avoid midday sunlight. The winter feeding adjustment scheme facilitates observation of the fish population during winter. Furthermore, during nighttime water exchange, the adjusted cage depth utilizes surface tides to promote water exchange and helps clean and remove waste from the aquaculture cage 30.

[0031]

[0032] A connecting pipe 42 is provided on the float frame 41, which communicates with the hollow part of the float frame 41 and is connected to the control component 16 through the first pipe body 12. The control component 16 has a pump body. A first connecting block 44 is provided on the float frame 41, which has a groove-shaped mounting hole for connecting to the bottom of the first base frame 10 or the second base frame 20. The pump body is a water pump, and the water volume inside the float frame 41 is controlled by controlling the water pump, thereby controlling the buoyancy of the float frame 41 and controlling the height of the buoyancy component 40 carrying the bottom aquaculture net cage 30 in the water.

[0033] The second base frame 20 has buoyancy and is equipped with a control component 16. The control component 16 houses a water pump, a positioner, a signal transceiver, a control unit, a water quality sensor, and a temperature sensor. The water quality sensor is connected to the water pump to detect the water volume being pumped. The control component 16 has a housing with a photovoltaic panel on top and a battery inside. This battery can be connected to a power generation component 13 on the second base frame 20, meaning the energy generated by the photovoltaic panel and the power generation component is stored in the battery to power various electrical devices. The power generation component 13 on the second base frame 20 is a wind power generator. A feeding device 15 is also installed on the second base frame 20, containing a certain amount of feed. The control unit within the control component 16 controls the feeding device 15 to feed the animals at set times and locations. Farmers need to replenish the feed regularly. A sensor can be installed within the feeding component 15 to detect the remaining feed level.

[0034] The first base frame 10 is arranged around the outer side of the second base frame 20, which can distribute the load between the second base frame 20 and the first base frame 10. The first base frame 10 increases the overall buoyancy, reducing the load-bearing pressure on the second base frame 20 and preventing the second base frame 20 from overturning or sinking due to the weight of the aquaculture cage 30 or the impact of wind and waves. The bottom of the first base frame 10 is connected to the buoyancy component 40 through the first rope 11, and the buoyancy component 40 can also be connected to the second base frame 20 through the first rope 11.

[0035] The first base frame 10 has elongated, strip-shaped floats arranged around it. Adjacent elongated floats are connected end-to-end to form a layout surrounding the second base frame 20. Vertical railings are arranged around the elongated floats, and buoys are located below them. The elongated floats can be connected to the first connecting rod 14 or to the first connecting plate extending from the second base frame 20, thus connecting the first base frame 10 and the second base frame 20. The first base frame 10 is arranged around the outside of the second base frame 20, upgrading from a "single buoy" to a "composite buoyancy system." The arrangement of the elongated floats around the second base frame 20 also creates a space between the first base frame 10 and the second base frame 20. This results in lower water surface fluctuations within this space, reducing the drift range of bait when it is placed in this area, thus lowering the probability of bait waste.

[0036] The aquaculture cage 30 has at least two cage rings 32 with a spaced-apart circular structure. Adjacent cage rings 32 are connected by a cage main rod 31. The cage rings 32 and the cage main rod 31 form a cylindrical structure and are covered with a net. The cylindrical cage with no sharp edges formed by the cage main rod 31 and the cage rings 32 can evenly disperse the impact force of water flow, reduce the generation of eddies, and reduce the risk of cage deformation. The cylindrical structure helps to form a spiral water flow during water exchange, accelerates the exchange of water inside and outside the cage, increases dissolved oxygen by 15%-20%, and improves the efficiency of metabolic waste discharge. The number of cage rings 32 can be selected according to the actual cage size to ensure the structural strength of the cage.

[0037] A first float 34 is provided in the middle of the net cage ring 32. A rotatable support rod 33 is provided between the first float 34 and the net cage ring 32. An extension plate is provided on the outside of the support rod 33. The support rod 33 can strengthen the net cage ring 32 and reduce the probability of deformation. At the same time, the support rod 33 is linked with the water flow or wind. The swing may promote water exchange around the net cage, increase dissolved oxygen, prevent local water quality deterioration, and promote the healthy growth of fish. During the swing of the support rod 33, the extension plate on its side swings, which can effectively drive away fish-eating birds such as seagulls and cormorants through dynamic visual interference or accompanied sound, reducing their predation on farmed fish and reducing economic losses. More importantly, after the feed is put down, it is guided into the aquaculture net cage 30 below by the support rod 33 and the extension plate, thus realizing the sinking path of the feed and preventing the feed from scattering quickly.

[0038] The second base frame 20 is surrounded by a first connecting rod 14 or a first connecting plate, which is used to connect with the first base frame 10.

[0039] Example 2:

[0040] See appendix Figure 4 Appendix Figure 6 As shown, this embodiment provides an optimized solution based on the solution in Embodiment 1: the aquaculture cage 30 is divided internally by a separating component 50. The separating component 50 includes a second float 53, a second separating mesh plate 52 surrounding the outer side of the second float 53, and a first separating mesh plate 51 surrounding the outer side of the second separating mesh plate 52. The first separating mesh plate 51 is placed inside the aquaculture cage 30 and connected to it. By setting the separating component 50 inside the aquaculture cage 30, different individuals of ribbonfish within the aquaculture cage 30 can be separated, solving the problem that ribbonfish are ferocious carnivorous fish, and the size difference between individuals can easily lead to fighting when aquaculture is carried out at high density. The second float 53 ensures that the separating component 50 maintains its posture in the water, reducing the downward displacement and deformation of the surrounding second separating mesh plate 52 and first separating mesh plate 51 under load.

[0041] Both the first separating mesh plate 51 and the second separating mesh plate 52 have mesh openings, but the mesh opening diameters of the first separating mesh plate 51 and the second separating mesh plate 52 are different. Setting the mesh openings of the first separating mesh plate 51 and the second separating mesh plate 52 in a proportional manner can guide the distribution of water flow during water exchange. For example, when the mesh opening of the first separating mesh plate 51 is larger than that of the second separating mesh plate 52, the flow rate of water passing through the first separating mesh plate 51 is larger. This makes the fluid flow velocity around the first separating mesh plate 51 and the second separating mesh plate 52 different, which promotes the movement of excrement and other waste above the separating component 50. This solves the problems of metabolic waste accumulation on the separating component 50 and overall dissolved oxygen uniformity. In addition, the effect of different flow velocities helps to promote the movement of fish and solves the problem of reduced density per unit space after stratification, avoiding the problem of local hypoxia, especially when fish gather at night.

[0042] A buoyancy support member 55 is provided below the first partition mesh plate 51. The buoyancy support member 55 has a hollow interior with a float. The upper end of the buoyancy support member 55 is connected to the first partition mesh plate 51 through a buoyancy connecting rod 551. The buoyancy support rod 55 can provide buoyancy support for the first partition mesh plate 51, preventing the edges of the first partition mesh plate 51 from deforming excessively downwards, and ensuring that the relative horizontal height of each first partition mesh plate 51 is consistent to ensure effective internal space division.

[0043] Example 3:

[0044] See appendix Figure 8 As shown, this embodiment further optimizes the design based on embodiment 1 by providing a first counterweight at the bottom of the aquaculture cage 30. This enables the aquaculture cage 30 to maintain stable and safe operation in complex aquatic environments, preventing it from overturning.

[0045] A third float 60 is connected to the side of the first base frame 10 via an auxiliary connecting rope 61. A loop is fitted on the auxiliary connecting rope 61 between the third float 60 and the first base frame 10. A first counterweight 62 is suspended on the loop. The third float 60 is connected to a second counterweight 63 via an anchor rope. The second counterweight 63 is placed at the bottom of the water area to control the position range of the first base frame 10 and the inner second base frame 20 in the water area. By setting the third float 60, it can float with the first base frame 10, but its floating range is controlled. This prevents the aquaculture equipment from floating out of the preset aquaculture area in the sea, causing the ribbonfish to be unable to adapt to the new water area. When it is necessary to change the water area, the second counterweight 63 can be removed, and the first base frame 10 with the equipment can be towed by a ship to the new water area. In this process, the third float 60 can act as a buffer to prevent the first base frame 10 from direct contact with the ship equipment, reducing the damage to the aquaculture cage 30 or the first base frame 10 caused by contact collision.
